TANK HEATER.

Application filed February 24, 1921.

To aZZ whom it 711.61.7 concern:

Be it known that I, Hrnaar A. citizen of the United States, residing atKnoxville; in the county of Knox and State oi Illinois, have inventedcertain new and useful Improvements in Tank Heaters, 01 which thefollowing is a specification.

This invention relates to means for heating the water in stock-wateringtanks and has for its object the provision of simple and inexpensivedevices whereby the water will be thoroughly heated and a circulation ofthe water in the tank set up so that the entire body of water will beraised in temperature and freezing of the same prevented. The presentinvention relates more particularly to the means for creating acirculation of the body of water in the tank.

The invention is illustrated in the accompanying drawing which shows aperspective view of the improved heater with parts broken away.

The casing of the heater comprises a ver tically disposed portion 1 fromone side of which extends an offset 2 whereby the casing is given astepped formation and within the vertically disposed portion 1 is avertical partition 3 having a slot or notch & in its lower edge. A fueltank or reservoir 5 is supported in any convenient manner within themain body of the casing at that side of the partition 3 more remote fromthe burners and a feed pipe 6 extends from said tank or reservoirthrough the slot or notch 4 over the-bottom of the casing to a pointwithin the offset or step 2 where it communicates with branches 7leading to oil burners of any preferred or well -known construction.Around the burners are chimneys or flues 8 whereby the flame and heatfrom the burn ers are directed against the top of the offset or step 2,as will be readily understood. Over the vertically elongated portion ofthe casing, I place a cover or lid 9 which has a horizontal plate 10resting directly upon the top of the casing and provided withperforations 11 therethrough to permit the air to enter and leave thecasing without acquiring such a strong draft as will tend to extinguishthe flames at the burners. In the ends of the lid or cover are shownopenings 12 which furtherserve to break up the air currents whilepermitting the entrance of suflicient air to support combustion but theentire ends of the cover may be open if preferred.

Specification of Letters Patent.

Patented Mar. 7, 1922. Serial No. 447,422.

Resting upon and extending across the top of the step or offset 2 is awater jacket 13 which may conveniently be constructed of sheet metal andhas a depending wing or branch let at each end. The said jacket willpreferably be of the same width as the offset or step so that oneside ofthe jacket will bear directly against the vertical wall of the mainportion 1 of the same. The opposite side of the jacket is open, as shownat 15, and the lower end of each depending wing or branch la is open, asshown at 16, and disposed at a substantial distance below the top of theoffset so as to be accessible to the water in the lower portion of thetank. It will be readily noted that the jacket provides a flue extendingupwardly at each side of the ofi'set and across the top of the samethrough which the water in the tank may circulate. The contactingportlons of the oifset and the water tank may be welded to preventdisplacement of the water back.

In using the device, the entire heater is placed in the tank so as torest upon the bottom of the same and the water level should be above theoffset but below the cover or lid 9. y removing the cover and shiftingthe partition 3 close to the reservoir or tank 5, access may be had tothe burners so as to ignite the same and the partition may then bereturned to its normal position closer to the offset than to the tank.The cover may then be replaced and the device will operate without anyfurther attention as long as a supply of fuel remains within thereservoir. The heat from the burners playing directly upon the top ofthe offset will quickly raise the temperature thereof to a high degreeand will, consequently, heat the water contained between the said topand the top plate of the jacket 13. This water, of course, will flow outthrough the open side 15 of the jacket and will be replaced by coolerwater rising through the end branches or wings 14: of the jacket whichin turn will be heated and flow out through the opening 15. It will thusbe seen that a circulation is set up within the tank so that the entirebody of water will be drawn through the jacket and exposed to theheating agent and freezing of the water will be thereby preventec. Thedevice is exceedingly simple in its construction and may be readilyproduced and applied at a low cost. The heat developed Within the casingcasing and be closed by the Will play upon the sides of the same andwill thu act directly upon the body of Water Within the tank so that thedesired tempera ture of the Water may be economically maintained. Afterthe fuel is ignited at the burners, the hot air will be deflected by thetop of the offset of the casing and Will flow to the space betweenthesame and the partition 3 and Will rise through said space and escape 7through the openings in the cover Wl1ll6 cooler air will be drawn inthrough other openings and pass down through the space containing thereservoir and thence through the slot or notch 4 to feed the burners asfully set forth in an application executed by me January 29, 1921. Thedevicemay be made in any desired proportions so that it may be used in atank of any size.

Having thus described the invention What is claimed as new is:

1. In a tank heater, the combination of a casing, a heater disposedWithin the casing, and a Water jacket extending transversely over thecasing and having a central portion resting upon the casing directlyover the heater and dependingend branches fitting close against thesides of the casing, the said branches being provided with inletopenings at their lower ends and the central portion of the jacket beingprovided With an outlet opening. r v i v 2. In a tank heater, thecombination of aoasing having a stepped formation, a heater disposedWithin the casing to play upon the top of the step thereof, and aninverted U- shaped shallow Water jacket resting upon the top of the stepand bearing closely against the sides thereof, theintermediate portionof said jacket being open at its front side and the endsof said jacketbeing open at their lower extremities, the top Wall and outer end Wallsof said jacket being parallel with the adjacent surfaces of the casing.

In testimony whereof I affix my signature.
